The present invention provides a temperature controlled energy transparent window or electrode used to advantage in a substrate processing system. The invention also provides methods associated with controlling lid temperature during processing and for controlling etching processes. In a preferred embodiment the invention provides a fluid supply system for the lid which allows the fluid to flow through a feedthrough and into and out of a channel formed in the window or electrode. The fluid supply system may also mount the window or electrode to a retaining ring which secures the window or electrode to the chamber. In another aspect the invention provides a bonded window or electrode having a first and second plate having a channel formed in the plates so that when the plates are bonded together they form a channel therein through which a temperature controlling fluid can be flowed. An external control system preferably regulates the temperature of the fluid.

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

According to one example a linear translation stage is provided. The linear stage includes a first portion (e. g. , a base portion) and a second portion (e. g. , a stage portion) configured for relative translation with respect to each other. One of the first portion or the second portion has a coil associated therewith and the other of the first portion or the second portion has a magnetic source associated therewith. The magnetic source may include one or more magnets to produce a magnetic field that generally encompasses the coil such that current through the coil causes a force on the coil, thereby causing translation of the first portion relative to the second portion.

According to one aspect, a monolithically formed rotational flexure bearing is provided. In one example, the rotational flexure bearing includes a stationary portion, a rotating portion, and at least one flexure element. The stationary portion, rotating portion, and at the at least one flexure element are monolithically formed. The rotating portion is coupled to the stationary portion through the at least one flexure element, thereby allowing relative rotation of the rotating portion with respect to the stationary portion. The stationary portion may include a center axis portion along a rotational axis of the flexure bearing and opposing fixed plates on either end, the rotating portion positioned between the opposing fixed plates. The flexure elements may extend from the center axis portion to the rotating portion. The flexure bearing may include between 2 or more flexure elements.

A solar concentrator assembly includes a pair of rails coupled together only by one or more backpans which are mounted between the pair of rails. The rails are configured to resist a portion of a cantilever deflection along the length of the rails. The backpans seat solar concentrator arrays and are configured to provide torsional rigidity and deflection resistance in at least one direction orthogonal to the cantilever deflection.

A method for electrohydrodynamic printing wherein multiple colors are printed by discharging the receiving medium by reverse-sign corona discharge, then charging the receiving medium by corona discharge, and then printing the first color. The receiving medium is then discharged, and charged a second time by corona discharge. The process is repeated for each color used in the printing. As a result, the colors are printed in their intended locations without deflection even if the intended location is a dot of previously deposited color.
